. CENTRIFUGAL FIXTURE.

Application filed May 4,

In all the processesof evaporation and distillation, and throughout thearts of fluid purification and rectification, as by separators, it isboth assumed and desired that `the fluid evolved or treated shallleave'the ed as to induce a strong centrifugal ac tion Within the escamgor discharged fluid to the Y end that the foreign substances and heavierconstituents are effectually and certairly removed Cfrom outgoing orescaping Huid. The aforesaid vforeign substances or heavier constituentsare suitably discharged from the devices externally thereof.

The invention has among other objects to perfect and refine the detailsof devices for carrying out processes of purification, and in theVsimplest and most reliablev manner for A the performance of the process.With these and other objects in view, the specific character of theinvention will be more readily understood by reference to theaccompanying drawings which form a part of this specification, and inwhich: i Y Fig.- 1 is a longitudinal vertical section of one form ofcentrifugal fixture embodying this invention. f

f F v The present inventlon, which embraces certain structural featureswhich are con- `Cerned with features heretofore referred to,

embraces tuyeres, that is, rotation inducing members, which may be of anumber of different constructions but are generally typified by themember 8 herein illustrated.

Said member 8, as herein shown, is comi posed of a top ring 8a, aplurality of tangentially positioned tuyre blades 8b, and an imperforatebottom plate or disc 8. The inner edges ofthe blades substantiallyconform to or meet an imaginary cylinder indicated by the circle 8d,Fig. 2, and this'is true also of the inner periphery of the top ring 8*.The tuyre blades being tangential -to the aforesaid imaginary cylinder,present tangential impact surfaces to the incoming fluid. While otherforms and arrangements of tuyre blades than those illustrated by wayK ofexample only, may 'be employed, vin

any case the blades form long and relatively thin slots or tuyreopenings 9. and hence collectively subdivide the iuid into a pluralityof thin streams that substantially parallel the axis of the tuyre ring..The vapor or other fluid approaching'the fixture impacts the surfacesof the tuyre blades, and is directed by'such surfaces into the describedrelatively -thin streams. These sov i streams enter the substantiallycylindrical tuyre ring tangentially and, encountering the annulararrangement of blades, combine to set up a very rapid'whirling actionwithopenngs the streams of fluid impact the inner surface of the tuyreblades. These surfaces being preferably tangential in position, conformto the normal angle of incidence of globules of liquid or particlescarried by 1in the tuyre ring. O n'entering the tuyre the streams offluid. These globules instead f of being swept away are left or retainedupon the inner surfaces ofthe tuyere blades. The accumulationof suchimpurities isproportionate tothe quantity thereof present in the Huidpassing through the fixture, and,

as the deposit takes on the general whirling action ofthe body or iiuidWithin the tuy're ring, that very whirling'action insures the retentionof the accumulated substances at vthe lperiphery of the whirling body,that is,

on theinner periphery of the tuyre ring. Followin the general movementof the whirling ody within the tuyere ring, the purified liquid or gasmoves axially towards the outlet 10. The upward sweeping action liftsthe deposit of impurities to the top'of the tu re ring and into therace-member 14.

The tuyre ring member 8, the component4 parts Sof which have beenheretofore described, is mounted in a chamber of cast metal, which in.the construction shown in Fi 1 has flanges 18, 19, at its opposite ens, through which coupling( connections are made with the inlet andoutletpipes, 7, 10," which, are, respectivel provided with coupling flanges 7,`10,t e flanges of the casing being, if desired, connected lwith saidcouplmg flanges by bolts 21, whose ends are threaded to receive nuts 22.The race-way 14 is herein shown as formed in the casing 16 and the.latter is cast around the ring 8a ofthe so-called tuyre member 8. Thisprovides avery convenient and rigid construction, and `wherein thetuy're member is reliably and permanently secured in integral manner tothe interior of the casing, within which latter said tuyre member isthus sus'- pended with suliicient space surrounding the tyure blades andthe bottom 8. Inthe modification shown in Figs. et and 5 the tuyremember 8 is provided with a bottom 8c of suiiicient thickness tocooperate at its circumferential edge with inwardly rojectin radial lugs8f, Vthe latter being ormed uring the process of casting the casingaround the tu re member 8 so as to engage and'support t ie latter inproper position within said casing.y In th1s ,construction, also, thewalls of @the casing are in the casting operation formld with aninwardly projectingv annular portion'25 ywhich surrounds and embracesthe lower extremity of the tuyre rin so that the latter is held or`suspended wit in the casing 16 by the lugs 8f and the annular rib orprojection 25. In th1s particular construction the pipes 7, and 10,which, respectively, convey the fluid into and discharge it` from thecasing 16, are

Athreaded into the latter.

In the modification illustrated in Fig. 6, the tuyre member '8 isprovided with a bottom 8c, tuyre blades 8", and an upper' ring 8a, whichlatter is cast within the casing 16, as described in connection withFig. 1.. Under this construction I have shown an adjustable innerwall'or bottom member 30, which is swiveled to a screw stem 31, inthreaded engagement with a hole in the 'within said casing in thebottom' 8, said stem having preferably a polygonal end 32 "forengagement by av wrench or other tool. The adjustable bottom 30 isherein shownl as provided with a" cone-member 35,l an,d is confined tothe stem y 31 between ahead 364 on the latter, and a washer 37. Whenthes'tem is turned the 'y bottom may be moved to adjust suitablyl thearea of` the openings through the tuyre rin I'the constructionillustrated in Fig. 7, the' tuyre member 8 is cast with the inwardlyprojecting lugs 8t for engagement with the bottom 8? and with the.inwardly projectingl cast annulus or rib 25 for engagement wit the oposite end portion of the `tuyre ring, where y the latter is cast withinand held flrml by the casing 16 in the same manner as eretoforeAdescribed with reference to Fig. 4. In the constructionment of thearea.of. the tuyre openings is effected from' the inside of the casmg 16 ina.- construction wherein the tuv re lrin is held l 'or sustained withinthe casing byt ei expering, s that said ring becomes in effect anintegral structure with the casing.

Claims: l v 'i 1. A centrifugal fluid purifying device, comprising, incombination, a casing, a hollow'ring member thereiny and an internallysmaller coaxial tuyre ring portion secured I process/of casting thecasing, and adapted to whirlinglyfd'irect the fluid into andl throughsaid member, said hollow member having a still smaller central outletaxially remote from said tuyre portion and also having aperipheraldischarge nozzle.

2. centr1fugal llu1d purifymg dev1ce, comprising, 1n comb1nat1on, ac1rcumferential series of tangential tuyere blades, a `ring-y -dient.ofcasting the latter about the tuyre at one end of said blades, and acasing cast about said blades and ring, sidring being embedded in themetal of said casing during the recess of casting, and a hollow ringmember in said casing of larger diameter than the diameter of saidtuyres, and provided with a tangential outlet. w

3. A centrifugal fluid purifying device, comprisingfin combination, acircumferential series of tangential tuyre bla-des, a bottom member atone endyof said blades, a ring member at the'other end thereof, anexternal `enclosing casing for saidblades -and rings which iscast'around said ring` and permanently embraces it, and an adjustableplate located Within said tuyres and movable by means accessible fromwithin the casing to vary the area of the tuyre openings.

4. A centrifugal Huid purifyin device,

' comprising, in combination, a cir'cu ar series tuyre blades and castabout said blades so as to secure them permanently in position 10therein, and a hollow ring member in said casing having a tangentialdischarge opening.

In testimony whereof I have hereunto set my hand this 30th -day ofApril, A. D. 1925.
